yes mine is a korean wii soft modded version 4.0u and here is how it worked FOR ME...
i was unable to access the mii channel or the photo channel the error was "this channel can't be used" so
i deleted the previously installed HBC
i downloaded bannerbomb and followed the instructions, very easy, can't mess it up, just make sure you are using v1.
then followed the instructions on Cannot access Mii channel on Korean Wii at JOKERz Lounge the only difference i had to use "anytitledeletermodv6"
and i had to turn it off and back on, two times because in the first one it freezed.

IT MAY NOT BE THE CASE FOR YOU but i will still mention it just in case..
at some point during my very exhausting 12 hours straight experience i had to do "format system memory"
and got stuck with preloaded system menu error to overpass this i followed the instruction on this threadhttp://www.wiihacks.com/general-home...ystemmenu.html but by that time, it was 2 in the morning and didn't know what went wrong and how i got fixed but glad i went to bed knowing my kids can still play even if they can't save, and then early morning i manged to reinstall the hbc and got the mii channel working..
i hope my experience will help some one....
just remember that when the instructions says "reboot" or "turn it off then back on" sometimes you have to do it twice, i think that was the trick for me.
